RTX 3090 vs A100 tensorflow performance

When I searched how to estimate GPU performance I found this answer on stackoverflow, which contains the following code:

After Nvidia released a bunch of new generation GPUs I wanted to compare their performance.
To measure fp16 performance dtype was changed to tf.float16.
To benchmark matrix multiplication in tensorflow 2 compatibility mode was used. It can be enabled by replacing


So final results for tensorflow 2.4.0 are in table:
